Canon EF 70-200mm f4L IS USM Telephoto Zoom Lens

Capture the far-off action of fast-paced sports or zoom in for an intimate portrait with the Canon EF 70-200mm telephoto zoom lens. The L-series lens offers an Image Stabilizer that provides up to four stops of shake correction--a first for Canon IS lenses. The use of fluorite UD lens elements, meanwhile, produces an excellent optical performance in terms of resolution and contrast. Add in a sturdy housing with water- and dust-proof construction and you have a lens that's both portable and high performing. Other details include an f/4 maximum aperture, a ring-type ultra-sonic monitor (USM) that enables quick and quiet autofocusing, compatibility with circular polarizing filters, and a lightweight body. The lens carries a one-year warranty.
